Moving Lightroom Library

I run the latest version of Lightroom Classic on an M1 MacBook Pro with 2Tb of memory, about half of which is in use; I want to transfer my library of about 120,000 images that’s just under 5Tb on an external drive to a new, larger external drive. My catalogue is on my desktop. I’d really appreciate having the simple, idiot-proof instructions on how to do this. Thanks!

    Move the entire folder structure of your photos to the new drive, using your operating system, keeping the folder structure hierarchy and folder names unchanged; this part in bold is critical. Do not move things around inside the folder structure. So if on the old drive, all of your photos are on Drive #1 in folder “My Photos” in its subfolders, then after the move all of your photos should now be on Drive #2 in the folder “My Photos” and its subfolders. Then point the LrC Catalog to read photos from the new external drive, follow these instructions (in particular see Figure 4 and associated text).
